Malaysian Palm Oil Board
Diagnosis of Ganoderma infection in oil palm is based on the presence of basidiomata of the pathogen on the stem base or frond bases or roots. To conduct various studies on Ganoderma in oil palm, a Ganoderma selective medium (GSM) was developed. The medium was used to isolate the pathogen from any part of the […]
A weighed test portion of the sample is diluted in xylene. The solution is introduced in aerosol form into an argon plasma of the ICP OES spectrometer (Figure 1). The phosphorus content is calculated with reference to a set of calibration solution prepared. The wavelengths used are 213.6 nm and 178.3 nm. Main Research: Yung […]
The sample is diluted with kerosene using a 1:1 weight ratio. The resulting solution is directly injected into the plasma of the ICP OES spectrometer (Figure 1), and the content of Na, K, Ca and Mg is calculated with reference to a set of calibration solutions prepared. The wavelengths for the analysis of Na, K, […]
The biodiesel sample is diluted with a xylene solution. The potassium contentof the sample is directly determine by flame atomic absorption spectoromery (Figure 1) at a wavelength of 766.5 nm with reference to a set of calibration solutions prepared from a potassium organolmetallic salt dissolved in a mixture of xylene and stabilizer. Main Research: Yung […]
The biodiesel sample is diluted with xylene solution. The sodium content in the sample is directly determine by flame atomic absorption spectrometry (Figure 1) at the sample wavelength of 589 nm with reference to a set of calibration solutions prepared from a sodium organolmetallic salt dissolved in a mixture of xylene and stock oil. Main […]
